Dunn & McCuskey S&W Charges Analysis April 15,2008/April 7,2009 Page� In 2004 we had advised the Williamsons that a sewer connection fee based on the 1973-1 Hackberry project would be due. Because the Glendale Cove project subsequently included extension of sewer laterals and water mains that the City would then own, staff determined it would be most consistent with City policy to establish sewer and water connection charges for the Williamson property (and any other existing homes that would connect to the Glendale Cove lateral system) based solel�� on the costs of the Glendale Cove project, disregarding the Hackberry project. The 8 new lots in the subdivision would not be subject to the Orono connection charge because their developer paid the entire costs of installation of that system. Per discussions with City Engineer Tom Kellogg and City Administrator Ron Moorse, a formula was established for assigning conriection fees for the Glendale Cove sewer and water system, based on the prorated line item costs of sewer or water facilities installation plus 1/2 the cost of providing basic access for utility maintenance. Cost figures were based on the City Engineer's Cost Estimate for Financial Guarantee dated June 12, 2006. The formulas for sewer and water connection charges were as follows: Williamson - Sewer Connection Fee Formula: 1) Sanitary Sewer Improvements: $35,450 $35,450 2) ]/2 of Base maintenance roadway costs $]0,000 common excavation 2,350 subgrade excavation 11,440 Class V Base 5.000 fabric $28,790 a 0.5 14,395 3) Restoration 4,000 c.y. @ $2.50/c.y. a 0.5 5.000 $54,84� Sewer Connection Fee=$54,845/9 base dwelling units= �6,094/unit Williamson - Water Connection Fee Formula: l) Water Main Improvements: $47,255 $47,255 2) 1/2 of Base maintenance roadway costs: $10,000 common excavation 2,350 subgrade e�cavation l 1,440 Class V Base 5,000 fabric $28,790 x 0.5 14,395 3) Restoration 4,000 cy. @$2.50 /c.y. x 0.5 5,000 $66,650 � Water Connection Fee=$66.650/9 base dwelling units =$7,406/unit It was concluded that these fees should be included in the 2008 Fee Schedule for the Glendale Cove sewer project. While we did not anticipate that there would be other connections coming into this system, it would be appropriate that the connection fee be established now rather than later. These would then follow the standard annual inflationary increase program. Note that in addition to these connection charges, Williamson also paid a
